Zusammenfassung:	To provide a polyester resin which is excellent in yarn quality characteristics such as thermal adhesiveness when used as a binder fiber and characteristics when used as a non-woven fabric.SOLUTION: A polyester resin is composed of a dicarboxylic acid component and a glycol component. In the total acid component, a content of an isophthalic acid is 8-30 mol%, the glycol component contains ethylene glycol, and contains diethylene glycol and triethylene glycol, and in the total glycol component, a content of the triethylene glycol is more than 0.1 mol% and 5 mol% or less.SELECTED DRAWING: None 【課題】バインダー繊維として使用した際に、熱接着性等の糸質特性や、不織布等としたときの特性に優れるポリエステル樹脂を提供する。【解決手段】ジカルボン酸成分とグリコール成分からなるポリエステル樹脂である。全酸成分中、イソフタル酸の含有量が８～３０モル％であり、グリコール成分が、エチレングリコールを含むとともに、ジエチレングリコールとトリエチレングリコールを含み、全グリコール成分中、トリエチレングリコールの含有量が０．１モル％を超え５モル％以下である。【選択図】なし
